Fired up the engine today!

It may be just a faulty pcm. Check for correct power at the wire right out of the pcm instead of the end. If it's not enough there, before you went any frather I'd def. call wait for me and see it they have any idea's, Otherwise I'd say pcm issue-not software, but hardware.....It's never easy is it :x

Talked with Jesse at Wait4Me, and he seems to think it is a grounding issue to the PCM. He may be right, I was having some strange ground issues when I first started to crank the engine. I will go back and check some of the grounding issues. I may have forgot to connect some ground wires to the chassis? :-k

I wanna say my harness had three ground wires all of which I brought to the firewall where the factory grounds run to. Then I did the battery straight to the block and then the block to the frame with a big ground strap.

Well, it's not a ground issue. I tried all the things Jesse suggested. Looks like my PCM is bad. So, now I'm debating on just connecting the fuel pump to the ignition +12V signal (via relay) or getting another PCM. I'm concerned about the safety of the fuel pump always running with the key in the on position. I Wished I had another PCM just to test..... :-k

i thought all the outputs were pull to ground... not 12v out....

Thats great info boss. Im sure its really going to help some folks with an LSx swap.
Aside from the minor electrical problem, whats keep you from taking it for a little spin?

 

[basketcase]

DON'T wire it always on!

I'll see if I can find pics to send to you when I get home of a car that had the fuel pump always on.

 

[StreetBu]

Ok Phillip, Where's the update on the car?

 

[388bu]

He's been driving the tires off it and his son hasn't had a single chance to. :lol:

I wish!! :lol: Actually, we haven't driven it yet because I do not have the floor shifter/cable installed. I need to get the floor cleaned up (rust removal) and patched up. Then I will install the carpet and console. Also, I need to swap out the 2.41 or 2.56 gears for some 3.23's that I got.

Not to mention going to basketball games, soccer games and now softball is starting up.

I know I've been really slow getting this project done, but I'm just not in a hurry for my son to drive it. I'm letting him get some driving experience with my Toyota Camry right now. The Malibu will be almost 2x the HP of the Camry, so he needs some experience behind the wheel. lame_sign.gif :lol:

I have my son cleaning the floors this week with a wire wheel. We will decide what needs patching/repairing and the seal it with somthing like POR15. I still need to order interior plastic pieces. Got the money set aside, just need to order it.....

Oh, on the fuel pump issue..... I'm probably going to swap out the ECM with Jesse and see if that fixes the problem.
